Showerhead Adapter with Snap Ring to Prevent Hose Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shower head systems experience hose twisting or movement due to increased water flow speed, leading to reduced hose lifespan.
Innovation Solution
A shower head adapter with a body part connecting to the main shower head body and hose, featuring a snap ring, O-ring, and screw threads to secure the hose in place, preventing movement and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hose is connected directly to the main shower head body without additional securing mechanisms, then the device complexity is low, but the hose twists or moves freely when water flow speed increases, reducing reliability
Solution Approach 1:
The adapter is divided into multiple functional components: a body part with flow channel, a main body connecting part with protruding inner circumferential surface, and a snap ring as a separate securing element. This segmentation allows each component to perform its specific function while maintaining overall connection stability without excessive complexity
Solution Approach 2:
The snap ring is pre-installed into the first circular groove of the body part before the main body connecting part is assembled. This preliminary action ensures that the securing mechanism is already in place to prevent hose movement and twisting from the moment of connection, improving reliability without requiring complex assembly steps
2Reliability
If a snap ring with larger diameter than the protruding inner circumferential surface is used, then the hose connection stability improves, but the manufacturing precision requirements increase
Solution Approach 1:
The snap ring is designed with a localized diameter that is specifically larger than the protruding inner circumferential surface of the main body connecting part at the critical engagement point. This local quality ensures secure connection prevention while allowing standard manufacturing tolerances for the overall components, balancing reliability with manufacturability

AI summary
A shower head adapter includes a body part, which has one side connected to the inner circumferential surface of the inlet side of a main shower head body and the other side connected to a hose. The shower head adapter also includes a first circular groove formed along the outer circumferential surface thereof and a main body connecting part, which has an end on the other side protruding inwards from the inner circumferential surface thereof. A part of the inner circumferential surface is coupled to the outer circumferential surface of the inlet side of the main shower head body. A snap ring is inserted in the first circular groove. The diameter of the outer circumferential surface of the snap ring is larger than the diameter of the protruding inner circumferential surface of the main body connecting part.
